“…No removal for all PFCs was observed at pH 5 and 7. These results confirmed that the removal of micropollutants in the presence of nZVI is enhanced under acidic conditions, verifying the important role of pH in removal experiments with nZVI [31,32]. In ZVI system, following equations are known as main reaction mechanisms for pollutant degradation.…”

“…When nickel mass loading is too high, the contact area between nickel and iron will be decreased gradually because the ratio of iron becomes too low, which counteracts the reactive hydrogen production, electron transport, catalytic sites, and galvanic couple formation. Similar findings could be found in a study of Cu/Fe bimetallic particles for dechlorination [13,25]. Throughout this study, the effect of nickel contents on dehalogenation was simply and efficiently investigated.…”

We first report a mechanism study on the adsorption of Cu(II)-Cr(VI) binary mixture by a novel low-cost adsorbent, carbonized Eupatorium adenophorum. The influences by pH value, dosage, initial concentration, temperature, and adsorption time on its performance to absorb copper and chromium were investigated. The experimental data were fitted according to the Langmuir and Freundlich adsorption isotherm models, the pseudo-first-order kinetics, the pseudo-second-order kinetics, and the intra-particle diffusion model. The results indicated that when the reaction system was with its pH = 5, the dosage of carbonized Eupatorium adenophorum was 0.1 g, the adsorption time was 30 min, and the temperature was 25°C; the adsorption capacities for Cu(II) and Cr(VI) reached 27.62 mg/g and 9.68 mg/g, respectively. The process of carbonized Eupatorium adenophorum to absorb Cr(VI) is also accompanied by redox reactions. The Langmuir model and the pseudo-second-order model can better fit the experimental data. Observation by fourier transform infrared spectroscopy (FTIR) and scanning electron microscope (SEM) found no significant change of functional groups before and after the adsorption by carbonized Eupatorium adenophorum, and this adsorption process is mainly a physical adsorption.
